COUNTER-TURNING MACHINE.

Application filed October 25, 1820. Serial No. 419,190.

To all whom it may concern V it known that I, Finn) A. REARDON, a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Counter- Turning Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to power actuated machines for turning the counter portions of turn shoes, and is of the general type disclosed in the application of John E. Scott, Ser. No. 357,119, filed February 9, 1920.

This invention seeks to simplify the con struction of this type of machine and to provine certain modified forms of turning instrumentalities.

For a more complete understanding of the inventiontogether with other objects, advantageous details, and combinations of parts reference may be had to a complete description of one embodiment disclosed in the accompanying drawings, in which,

Fig. 9, is a detail plan partly in section of the counter spreading members and related parts. I V

Referring to the drawings A represents a machine pedestal of any suitable or usual form carrying at its upper end a machine head B. The head B comprises a substantially L shaped casing having a horizontal leg 1 and a vertical leg 2. The outer or forward portion of the horizontal leg 1 is beveled as shown at 3 and carries fast thereto an upwardly and rearwardly inclined horn 4. While as shown these parts are made separate, if desiredthey may be formed integral. The horn 4 has a pair of grooves 5 and 6 cut in the upper and lower faces thereof and merging at their upper ends at 7. At their lower ends grooves 5 and 6 merge in an open casing 8 in which is housed a sprocket wheel 9 carried on a shaft 10 mounted in a pair of cars, one of which is shown at 11, pro jecting into the casing 8 and fixed either to the horn 4 or to the leg 1 as preferred. Shaft 10 also carries a spiral gear 12 meshing with a mating gear 13 carried by a shaft 14 journaled in bearings 15 and 16 in the horizontal leg 1 of the head B. At its upper rearward end horn 4 has journaled in the portion 7 a hexagonal roller 17. An endless chain 18 passes about the sprocket wheel 9, and rearwardly about the roller 17. As shown more particularly in Fig. 2, each link of the chain 18 has a pointed end as shown at 19 which projects outwardly from the chain as the same passes about the roller 17 but is substantially in alignment therewith in other portions of its path. It should be also noted that the grooves 5 and 6 are deeper at their lower forward ends and become shallower toward the roller 17 so that the chain is completely housed within the horn 4 at its lower forward end and projects therefrom to gradually increasing degree adjacent the upper rear end thereof. The horn 4 has a longitudinal slot 20 passing laterally therethrough near its upper end in which is slidably positioned a block 21 (see Figs. 2 and 7). 22 is a supplemental shoe turning element having an upwardly and rearwardly directed shoe engaging forked projection 23, constructed to ride on the upper surface of the horn, and having a pair of plates 24 and 25 (see Fig. 3) which are bolted thereto by the bolt 26 and extend downwardly on either side of the horn 4 where they are made fast to the slide block 21 by pins or bolts as shown at 27. By this means the element 22 is mounted for limited sliding motion lengthwise of the horn 4. Between the plates 24 and 25 forwardly of the member 22 is pivoted at 28 a pawl 29. Pawl 29 has a forked extremity 3O adapted to engage in the spaces between the links of the chain 18 as shown in Figs. 5 and 6. Rearwardly of the extremity 30 is a downward projection 31 positioned latemu-y thereof and riding in a slot 32 out in the upper face of the horn 4 near its upper end. Pawl 29 also has an upstanding proj ection 32onwhich presses thev free end of a leaf spring 33 made fast at 34 to the turning element 22. Adjustably fixed to the upper face of the horn 4 is a plate 35 having an upwardly directed rearward extremity 36 positioned above the chain slot 5. Screws 37 and 38 fixed in the horn and passing through slots 39 and 40 in plate 35 provide means by which the plate may be readily adjusted and fixed-in adjusted position on the horn 4. A spring 41 fixed at one end to plate 25 and at the other end to the horn,

urges implement 22 tothe forward lower limit of its travel.

Shaft 14 above mentioned, which is the driving shaft of the machine, has fixed thereto adjacent the bearing 16 a spiral gear 45 which meshes with a similar gear 46 journaled on a pin 47 which forms the fulcrum of a lever 48. Lever 48 has an upwardly extending arm 49 which carries adjacent opposite ends bearings 50 and 51 in which is journaled a shaft 52. The lower end of this shaft has fixed thereto a spiral gear 53 which meshes with the gear 46 and at its upper end it carries a gear 54 which meshes with a similar gear on a shaft 55 journaled in the arm 49. Shaft 55 carries a gear 56 meshing with a pair of gears 57 and 58 carried by a pair of shafts 59 and 60.

Fixed to the shafts 59 and 60 are a pair of friction rolls 6]. and 62. Lever 48 has an arm to the end of which is attached a cable .66 by which means the lever 48 may be rocked about its pivot 47 to bring the rolls 61 and 62 closely adjacent the upper end of the horn 4. I

'Shaft 14 extends outwardly of the head B and carries a clutch mechanism of any suitable type shown at C. A bracket D is made fast to the rear face of the leg 2 and at its'outer' end carries an outer bearing for the shaft 14. as shown the clutch mechanism C comprises a conical friction wheel which may have frictional contact with a mating surface on a belt wheel 71. A rod 72 having a wedge 73 at its upper end engages a mating wedge collar 74, having a ball bearing 76 interposed between it and a fixed collar 77 adjacent the bearing of bracket D. Any other suitable clutch mechanism may be employed if desired, however,

as this forms no part of the present inventlon. The rod 72 projects downwardly and carries at its lower end a pin 78 riding in a curved. slot 79 in the rear, end of a treadle lever 80. Lever 80 1S ournaled at 81 on the pedestal A and projects forwardly where it 1s provided with a foot portion 82 in convenient position for the operator. Within the slot 79 is a block 83 which may be adjustably positioned therein by means of the "bolt 84. The top'portion of the vertical leg 2 ofrthe head B is provided with a forwardly and downwardly inclined guideway (see Figs. 8 and 9) for the reception of a slide member 91. Slide 91 may be adjustably fixed to its guideway by means of. a bolt 92 (see Fig.7). The under surface of slide 91 is dovetailed as shown at 93 in Fig. 8 and Slidably mounted therein is a second slide 94. Slide 94 has a projecting fin '95 formed with rack teeth 96 thereon which mesh with a gear 96 journa-led on a shaft 97 fixed in the portion 2. ills shownin Fig. 8, the right hand extremity of'shaft 97 is reduced in diameter as shown at 98 and sleeved on this portion is a long collar 99 having an enlarged head 100 at its inner end. This collar bears against one end of a collar 101 having on its other end a series of teeth 102 engaging mating teeth 103 on a hub of the gear 96. To normally keep these toothed portions in engagement, a spring 104 surrounding the outer extremity 98 of shaft 97 bears at its inner end on the outer end of the sleeve 99 and at its outer end againstthe inner face of a handwheel 105 threaded on the outer end of the portion 98. The collar 101 has fixed thereto a sprocket wheel 106 over which passes a chain 107. One end of this. chain is fastened to the end of a tension spring 108 which is. made fast at its opposite end to a lug 109 projecting from the inner face of the portion 2. The other end of the chain 107 is fixed to a cable 110 which is made fast at its lower end to an eye 111 on treadle lever-80. Also made fast to the eye 111 is a second cable 112 fastened at its upper end to a tension spring 113 which in turn is made fast to the lower end of the cable 66 above mentioned.

Carried by the forward end of-the slide 94 is an upwardly extending slotted arm 115 having a handle 116 at its upper end. Also fastened to the forward extremity of slide 94 is a bar 117 having an ear 118 at its forward lower socket 119 carried at the lower end of a pintle pin 120. Hinged on the pin 120 is a pair of counter-turning wings 121, 122 which are resiliently retained in position adjacent the socket 119 by means of a spring 121 engaging between the upper extremity of one of the wings and a nut 122"threaded on the upper end of-the pin 120, a lock nut 123 being employed to fix the nut 122' in adjusted position. Between the hinge elements. of the wing members 121 and 122 and sleeved on the pintle pin 120 is an arm 124 havingan upwardextension 125 to which is pivoted at 126 the forward end of an arm 127 which passes through the slot in the arm 115 and is pivoted at its rear extremity be tween lugs 128 and 129 fixed to the upper surface of the slide 91. Fastened to the wings 121 and 122, are universal joint elements 130 and 131 having mating elements 132 and 133 carried by rearwardly and 11pend pivoted within a ill against the bolt 1 16, the .pintle pin 120 carrying the wings 121 and wardly extending rods 13% and 135. These rods carry similar joint elements 136 and 137 with mating elements 138 and 139 the latter elements being fixed in lugs 140 and 141 made fastto the upper surface of the slide 91 by screws14t2 and 1 13, members 1 10 and 141 being held from rotation on the screws by pins in and 1&5 extending into the slide 91. By reference to Figs 1, 7 and 8, it will be observed that the bar 117 affords a movable support upon which the counterturning wings 121 and 122 are sustained by a double-pivotal connection afiorded by the upstanding pin 120 and a laterally extending pin extending through the ear 118 and the socket element 119, these pins having their axes in non-parallel and intersecting or substantially intersecting relation. By this means, the backward and forward movements in unison and reciprocal opening and closing movements of the counterturning wings are performed substantially about a fixed point and without bodily movement at the junction of the wings adjacent the shoe sole, which. is obviously a desideratum in the heel portion turning operation. Extending upwardly of the rear face of the portion 2 is a bracket E having adjustably fixed at the upperend thereof, and in line with the slide 9 1, an abutment bolt 146, a lock nut 1 17 thereon being used to hold the belt 146 in adjusted position.

The operation of this machine is as follows:

V7 hen the machine is at rest the parts are substantially in the position shown in Fig. 1, the slide 94 being in retracted position lower end of the 122 being retracted, and the rods 134 and 135 holding the outer ends of the wings turned forwardly about their hinged connec tion to their extreme forward position as determined by the adjustment of the slide 91 in its guideway. The lever 18 is also in its retracted position with its friction rolls 61 and 62 widely separated from the upper end of the horn 4. The turning implement 22 is at its lowered position on the horn 1 with its pawl 29 in engagement with the abutment 36, and its forked extremity 30 in engagement with the links of the chain as shown in Figs. 5 and 6. An unturned shoe is now placed in position with its sole portion bent over the end of the horn at the shank, the toe portion extending rearwardly, substantially as shown in Fig. 7. The operator then depresses the treadle 82 which, acting through the cable 112, rocks the lever 48 and brings the friction rolls 61 and 62 against the opposite surface of the sole thus clamping the sole between the chain and the rolls. The depression of the treadle also through the cable 110 pulls the chain 107 over the sprocket wheel 106, and

through the toothed clutch faces revolves the gear 96 which moves the slide 9 1- downwardly and forwardly and carries the wings within the counter of the shoe toward Ll position shown in Fig. 7. if any undue resistance be encountered the clutch elements between the sprocket wheel and the gear may slip against the action of the spring 104 and the final positioning of the wing members within the counter may be readily effected by hand manipulation of the hair dle 116 which may operate the slide 9 1- independently of the treadle, due to the slip connection as above noted. In this position of the parts, the supplemental turning implement 22 is closely adjacent the heel end of the shoe opposite the sole portion thereof. (in further depression of the treadle the block 8d contacting with the pin 78 raises the rod 72 and throws in the clutch (1 whereby through the drive pulley 71 rotation is imparted to the shaft 14. Through the connections before described movement is thereby imparted to the chain 18 and corresponding movement to the rolls 61 and 62 tending to feed the sole therebetween and progressively bend the same over the end of the horn 4:, the projections 19 of the chain links en aging the unfinished surface of the sole. 1 otion of the chain also imparts movement to the supplemental element 22 which engaging the heel portion of the shoe pushes the same upwardly. During this action of the parts the portion 117 carrying the counter-turning wings may move upwardly and rearwardly due to the slip connection with the sprocket wheel 106 notwithstanding that the treadle is held depressed. The upper end of the hinge connection is held from rearward motion by the thrust rod 127 which as before described is fixed to the slide 91 which is locked from sliding motion. The rods 13% and 135 are not permitted to yield rearwardly as they are also fastened to the same slide 91. The retraction of the lower end of the hinge connection therefore serves to tilt the wings 121 and 122 as a unit about their pivotal connection to the portion 117, and also serves to open the wings about their hinge connection. This motion presses the outer ends of the wings against the sides of the counter and serves to roll them outwardly and backwardly as the sole of the shoe is fed forwardly, this action serving to effectually turn the counter portions right side out. As soon as the projection 31 on the pawl 29 reaches the end of the slot 32, the forked extremity 30 is raised from en gagement with the chain, the spring 33 engaging behind the portion 32 holding it so raised. As soon as this takes place, the spring 11 retracts the element 22 until the pawl 29 impinges on the portion 36 which wedges the pawl downwardly and brings the lit) forked portion 30 again into engagement with the chain.

As soon as the turning action is complete the operator releases the treadle 82 whereupon the power actuation of the parts ceases, and the lever a8 retracts from sole engaging position. The chain 107 is also moved in a reverse direction by the spring 108, thus rotating the sprocket wheel 106, and retracting the slide 94 rearwardly and upwardly until it is contacted and stopped by the bolt 146, the slip. connection between the sprocket wheel 106 and the gear 96 permitting the spring to fully retract the chain even though slide 94. may have previously reached its rear limit of travel. The shoe with its coun ter turned may then be readily removed from the machine which is in position for a repetition of the same cycle of operations.

While this invention has been described in connection with a machine for turning the counter portions of shoes it is evident that certain features thereof are of utility in turning the toe portions also.
